The fan of the electronic device then starts to work, and pushes away the heat out of the casing, while providing a breeze for the internal components. When a device goes through such processing, then the CPU and the GPU start to generate heat and that is not a good thing for the electronics. Processing includes using video editing software or playing graphically heavy games on it. If the PC you are using is taking a lot of burden because of processing, then the fan makes a loud noise. This super easy to read guide will not only inform the reader about fan speed but how to control it. This is why, you need to be built in options to control fan speed, as well as third-party software options.
